Is Q4 Plus Turf Herbicide effective against yellow cup?

How and when do I apply?


Yes, Q4 Plus Turf Herbicide is labeled for yellow cup, also known as yellow mustard weed. The rate is 2.6-3 fl oz per 1000 square feet. This should mix in 1-2 gallons of water. This can be applied while the weed is actively growing before the soil temperature reaches 55 degrees Fahrenheit.
